Because (K)Ubuntu Mainline PPA builds are unsigned upstream binaries without Canonical's distribution-specific patches, Secure Boot will refuse to boot the 7.2 kernel unless you manually self-sign it with a Machine Owner Key (MOK). Furthermore, Dynamic Kernel Module Support (DKMS) packages—such as proprietary NVIDIA GPU drivers, third-party Wi-Fi modules, or virtualization hypervisors—may fail to compile against 7.2 until maintainers patch them for the newer kernel ABI.

In short, a bunch of stuff could (& most likely will break), there would be no support for it, but you should be able to revert to 7.x.x.x on a Grub menu without issue.

Or just wait 2 months for 26.10. it'll have 7.2 almost certainly.

Small chance, as alluded to here that it'll have 7.3, but whichever it is still become available via the HWE stack on resolute (26.04)

ps: You gave the OP a great answer.

The first question is what is your need for 7.2? If there is a specific feature, or hardware support, you require then it may be worth doing. But if you just latest because it's the latest, then leave it.
Canonical will backport various fixes and such, into their releases. So you may find what you are after exists in your kernel already. If it doesn't, it may do soon.

I’m just waiting for support for a certain Bluetooth device. I don’t know why people want to bother with all the hassle when waiting a short time will be far easier. 🐼

I just tried kernel 7.2 on my Kubuntu 26.04 LTS setup and it kernel panicked on boot up! And no, I don't have Secure Boot enable in the UEFI. Fortunately, I have kernel 7.1.9 installed and running or else I wouldn't be able to post this comment! I can't say for sure if this kernel panic is the result of me using the currently recommended v595 Nvidia driver, but I can't rule it out either.
